The annun- 8o view showinga portion of the clock-dial and ciator is also provided on its face below the 3o one of the contact-posts, and Fig. 9 is a face aforesaid clock-dial with a series of other view of one ofthe room-dials. dials J, such as are shown in Figs. 5, 6, and This invention relates to certain iinprove- 9, which maybe denominated as room-dials. ments in electrical annunciators for calling These dials are all numbered, consecutively, 85 or signaling purposes, designed more parl 2 3, the., to correspond with the number of 3 5 ticularly for use in hotels for calling guests the rooms of the hotel, one bein gused for each located in separate and distant rooms at a room. The construction ot these dials is previously-agreed time, which improvements shown more particularlyin Fig. 6. The dial, are fully set forth and explained in the folface J is setwith contact-'posts V, that extend 9o lowing specification and claims, and is dethrough to the interior of the case, andare 4o signed to be certain improvements on the deintended to be severally engaged by the arm vice for similar purposes, .tor which Letters F, Which is intended to be turned by the op- Patent of the United States No. 455,016 were erator so as to rest on and be in contact with granted to me on the th day of June, A. D, any one of said posts he desires. The posts 95 1891. V on any one of said room-dials correspond Referring to the drawings, the annunciain number and are numbered the same as the tor-case consists of a rectangular box A, contact-posts ci in the clock-dial E. An anadapted to be secured on the wall orsde 0f a nular ratchet R on the dial-face J serves to room or hotel oiiice, as shown in Fig. 2, and hold the armsF in contact with anyone ot the ico an ordinary battery G, as shown in said figure, contact-pins V with which they may be placed.

5o is designed to be located adjacent to the an' The hub of said ratchet passes through the nunciator and be connected therewith by dial-face J and SGleWS IltO the CaSe A and means of circuit-wires 1 3 l 5 6 7, It is dehas turned on its inner end, at the innerside of the case, the nut t' for holding the wire 4, leading toward the battery. The shaft I) passes through and is in contact with said ratchet-hub and has on its outer end the arm F and a button-head on its outer end and a Washer m on its inner end, held on by a pin q, and is provided with a coil-spring Y, sleeved thereon between said washer and the nut fr', for the purpose of permitting reciprocation of said shaft in its seat and for holding said arm F to its work on its dial and post.

The contact-posts a in the clock-dial E and the contact-posts V in the room-dials J are all connected by means of the wires 3 insuch manner that those numbered the same in each dial are so connected that when the Wheel ,IV of the hand H is in contact with one of the posts a the electric circuit will be closed with a post V of a corresponding numberand denoting the same time. Each room-dial J is connected by means of the wires 4t with contact-posts X in the bottom of the case, as .shown in Figs. l and 3. These posts are secured at one end in the front part of the case A and are detachably in contact at their extending ends with contact-springs Z, secured on thecross-bar r, so that the face of the an nunciator may be removed when desired. These contact-springs are connected by means of of the wires 6 with the battery G. rIhe arbor of the hand H is provided with a collar C, which is connected with a contact-post S, as shown in Fig. l, by means of Wire 7. The extending end of said post S is detachably in contact with a contact-spring S', secured to a bracket attached to the side wall of the case of the annunciator, so that its face may be removed. Said contact-spring S is connected bymeans of wire l with the call-bellK, forming part of the electriceircuit and located in a room above, andthe said call-bell is connected with the battery G by means of the wire 5.

D is a reciprocating bar arranged in the lower part of the case immediately above the contact-posts X, and is provided on its lower side with the depend-ing spring contact-arms O, which are arranged t0 be in contact with the said posts whenever the said bar D is pulled out and held out by means of the lug 71, hooking over the plate t, as shown in Fig. 4. In such case each spring-arm O willbe in contact with one of said posts. Said bar and all of its spring-arms O are connectedwith the spring-arm S by'means of wire Z and through the medium thereof with Wires l and o. This is for the purpose of simultaneously v ringing all the call-bells in the rooms in case each room simultaneously. In this illustration, Fig. l only represents one room-dial and one set of wires connecting it with the other device. Of course each additional room-dial would have a duplicate set of wires, so that a description of one set connecting one room# d ial'with the clock-dial will be sufficient for all.

l/Vhen it is not desired to set the annunciator for the purpose set forth, the arm F is placed so as not to be in contact with any one of the posts V, as shown by the broken lines in Fig. 9.

The manner of using the annunciator is substantially as follows: Should a guest in a particular room leave orders to be called at any particular time, the arm F of the roomcircuit will ring as long as said circuit con-- tinues, and thus call the guest at the time he ordered. If several guests all desire to be called at the same or at a different time, the various arms F will be set on the posts corresponding with the time they Wish to be called, and the electric circuit Will be closed 'for all said guest-rooms when the hand Il reaches the required hour or time.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

l. In the electrical annunciator shown and described, the combination, with the case A, of the Wires 6 4 3 7 l 5 and having a battery G and a call-bell K, forming a part of the circuit, contact-posts a, driven hand H, having the Wheel W for consecutively engaging said posts, contact-posts V, arm F for detachably engaging said posts, and ratchet R, all ar- IOO IIO
